Spray Master 450 Air Cooled MIG Guns, 450 A, 15ft, Tweco, 0.045in - 1/16in Wire

Thick-walled, three-layer conductor tube for higher electrical conductivity, act as “heat sink”. Heavy-duty thick-walled contact tip and diffuser increases tip life and decreases downtime with tip changes. Balanced to pivot at the center of the handle for ease of use in different welding positions, and thereby reduces operator fatigue. Extended trigger length to keep hand away from the arc to reduce radiated heat. Steel spring strain relief provides support to the Cablehoz® coming out the rear of the handle to minimize wire feed issues.
